This invention relates generall to window construction and more particular y cooperatin frame and sash structure in windows of the idin sash types.

It is we lknown'that there is a considerable problem involvedin producing air and dust tight joint'sor connections between window sash and frame members which will at Lthe portance in window construction, as applied Jamming or sticking eiects, tive of manipulation is to provide a window frame `ness an ease of operationand, in

obviate rattling and creaking noises charac- I same time .provide a suiiicient iexibility and smoothness of fitto permitready movement of the sash in the frame'in opening or closing the window.` The problem involved is particularly troublesome in connection with hi h buildings because ofthe action of power u1 wind forces to which lofty structures are peculiarly-subject. It is also of special imto marine vessels and to vehicles, either in cars used on steam'or electric railroads, or in automobiles of the closed top typle, because of the mechanical vibration and t dows of the sliding sash type are used.

A general object of the present invention anddsash construction vwhich will be free tions referred to and which will combine a weather cof joint construction with readiaddition,

teristic 'of COnditions.

The invention comprises a window frame construction vwhich includes Va pairof guide prior constructions under certain members arranged to' exertspring pressure 4 or tensi0n against the interposed sash mem-l bers, the guide members and engaged sash members being provided with interengaged bead and groove members arran edl to slide f longitudinally relative to each ot er and being maintained intensioned contact under the pring vpressure of the guide'orframe meml `feature of'the inventionl,resides :in a

floating or ieldiig support ofthesash which is provide by'the 'resi ientgripping action ofthe framemembers. The oating or yielding support thus provided does away with and`insures relamovement thereof in the b ers under all conditions ofoperation. i

e distorting stresses andstra-ins to which windows in such. situations are subject. The problem is not, i'howev'er, confined to the special cases referred to but 'is applicable generally wherever winl double from the objecof the sash andi"- frameguide Imam-- u of glass in thevflanle;

a Another feature of the invention resides` in the provision of a beaded separating member for double sash members, each of which is movable. vThe beads are formed on opposite faces of-,the` separating members for engagement withgrooves formed forthe purpose' in the confrontingsides of the sash members. In this construction the resilient guide members engage the outside faces of the-sash members and press the sash members toward each other and'tlie'intervening sepa- .rating member.'

vAnother feature of the inventionresides in the provision of a removable transverse end sash barvto provide-for the placing of glass in osition in the sash.

till -another ,feature 'of the inveition resides in a simplified lifting and locking de- 'I vice'especially adapted for .use lwith the im proved sash construction. 'Other features of the invention will be hereinafter describedand claimed.

Referring to the drawings for a more detailed description of the invention, a window frame sash construction is shown in Figs. 1 and 2 of the drawings and includes an upper sash member 5 and a lower sash member 6 mounted to slide vertically in a window frame 7. An important feature of the invention resides in the or directing members 8 of the window frame 7, these members being formed with base flange members 9 adapted to be attached as at 10 to the window frame members 7. rlhe lguide members 8k eXtend outwardly from the supporting base 9 and are inclined toward each other, as is indicated in Fig. 2 of the The members 8 are formed of drawings.

as to have a spring metal and so arranged .tension or pressure exerted thereon by the nature of the material of which they are made and the formation which is impressed thereon in a suitable forming operation. The guide members 8 are unattached at their upper and lower ends so that the natural spring tension which is inherent therein is constantly exerted against the intervening window sash members 11 and 12.

In order to provide a wind, rain and dust proof joint between the guide members 8 of the window frame and the sash members 11 and 12 of the window sashes, the free eXtremities or edges of the guide members 8 are provided with beaded or tongued formations 13, the beads thus formed being arranged to enter and engage complementary formed grooves 14 in the outside faces of the sash members 11 and 112. The bead and groove members 13 and 14 extend throughout the length of the guide members 8 and the sash members 11 and 12, as will be clear, so that vertical sliding movement of the sashes 5 and 6 in either direction produces a sliding movement of the grooves 14 with relation to the bead members 13, as will be clear.

It will 4be seen that with the construction Idescribed, a relatively airtight and wind Vproof joint is rovided while, lat the same time, because o the floating supportof the sash members which is afforded by rthe tensioned guide or holding members 8, readiformation of the guidingness and ease of manipulation ofthe sash members 5 and 6 is produced.

It will be seen that the guide members 8 referred to engage the opposite outer faces of the sash frame members 11 and 12. In order to produce an equally secure joint with respect toV the inner surfaces of the sash frame members 11 and 12, a sash separating mem- Aber 15 isprovided which consists'of a sheet van intermediate portion of the laterally eX- tending members being provided with openings 23 formed to receive a bolt 24 arranged to lock -the window sash members at any desired elevation. It will be seen that the bead and groove construction produced between the separating member 15 and the engaged surfaces of the sash members 11 and 12 is effective to prevent the passage of air or dust between theparts. ln addition, the resilient nature of the separating|member 15 provides for a floating support of the window sash members and permits the tensioning action of the guide members 8 to center the window sash members at a balanced position therebetween. A separating or partition member 25 is utilized to fill the space between the upper rail of the lower sash and the lower rail of the upper sash when the sash members are in positions to completely close the window opening.

It will be seen that the hollow window sash members 11 and 12, which are formed of any suitable sheet metal which is satisfactorily resistant t'o corrosion, are supported com "pletely out vof contact with. any rigid part so thatno binding or jamming action ofthe movable parts can take place with the result that the window sash members are always capable of being easily manipulated.

A feature of the invention resides in its applicability to window openings wherein it is desired to provide an immovable upper sash and a movable lower sash, as in car window construction. tion is shown in Figs. 3, 4 and 5 of the drawings wherein an immovable upper sash member 26 is engaged by a metal bracket member 27 along the outer face of the vertical sash member 28. The sash 26 is retained in its elevated position by an angularly turned endportion 29 on the bracket member 27 upon which the sash 26'rests, Fig. 5 of the drawings.

In this construction, guide rails 30 are provided for cooperation with the verticalv sash .-31 of the lower sash 32.

as is clearly shown in An example of this construc- ...ses 8 previously described and are rovided at their extremities with bead mem rs face of bead or use. An example of this is shown in Fig. 6

I' as ing noises characteristic of already described, the guide window sash member 52 is posite sides by spring guide members53 and.

of the drawing wherein wooden guide rails of the old' construction have been removed and resilient sheet metal guide members 35 have been used in their stead. The guidey members35have laterally turned base portions 36 which are attached tothe wood window Aframe member 37. Grooved track members or strips 38 are attached to the opposite faces of the window sash member 39m such positions that the grooves or seats 40 formed in thetrack members 38L are engaged by the bead members 41 edges of the guide members 35.f The guide members 35are arranged to exert spring tensionor pressure against the grooves which are engaged by the bead members 41 formed thereon so that, as in the a plications ofthe invention already referredp to. the 'window sash member 39 is held in a tensioned floating position which prevents rattling and creak; window frame constructions heretofore known and used. v

' In Fig. 7 of the drawings the invention is shown asapplied to a window construction in "a closed automobile body. The vehicle body is vertically grooved as at.' 42 to receive the vertical .sash members 43 which are spaced apart from the adjacent surfaces of the groove 42 and held ina position therein by the action of thev guide members 44 attached at 45 `to the edges 46 of the window opening and extending into the opening 42 in the frame member on opposite sidesof the sash members 43.

members 44 ter'- minate in. bead members 47 which engage ooves 48 formed in the opposite outer suraces of the sash members 43. In this form of the` invention, preferably one of the guide members .44 is providedv with an extension 49 rtion 49 which forms a tubular.

ich the terminal member 50 of -a Fig. 8 of the drawings, anapplication ofthe invention is shown as made to the win` dow* construction of a Pullmancar. .The

formed along the outer.

spring clamped.

As in the cases tensioned tubular member 58. In` Figs. 7

and 8 a perforated'locking strip is provided with transversal 'elongated openings'62 for receiving theen of the lockin bolt 24,

In Fig. 9 .of thedrawings, t ere is shown an adaptation of the invention in which the guide members 63 are formed integrally with abase member64-which is-attache as at 65 to tlie lwindow frame member 66 and rovides a locking rail 67 intermediate the attached .portions thereof. -Ascin the other embodiments of the invention, the' guide members guide member' 53 is provided with i 63 terminate in bead members 68 which have sliding 'enga ement'with groovesl 69 formedv in the outer acesof the sash member 7. The locking bolt 24 engags, as in the other exam-- les, in tran versely elongated openings 62 gormed in th' locking strij 67.

In order to provide fort from the sash or the insertion of glass into the sash, the construction shown in Figs. l9 and 10 ofthe drawings is provided. The lower its ends with an elsash bar 71 is provided at e removal of glass bow'section 72, the upward extension` 73 of which isadapted to belreceived in ahollow vertical sash bar.70 and is clearly'shown in the drawings. The vertical arm 73 ofthe elbow. section 72 the lower end of .the vertical frame bar 70 by means of screws 75 which are capable o\f being .readily removed in `order is fastened Lin its-position in.

to replace a l broken pane of glass 76. It will be seen that f the vertical sect1ons 73 ofthe elbow members 72 are provided with grooves 77 ada ted to form seats for the grooves69 forme the vertical frame members 70;

` In Fig. 12 of the drawings, there is shown a form ofthe invention in which a. single slidable sash 78 is mountedtoclose or unclose a window opening 79, the sash being movable vertically to a position in the frame above the window opening.- The window frame 80. is

provided with spring tensioned guide menbers 81 throughout its length, both inthe area opening 79 and' to a distance 4othe vrlindowd a ve t e win ow openin ual in hei ht to the height' g eq g In ord able sash ber'82 is provided which 'is attached to a rotatable stem 83 mounted in a central portion of either the upper or lower railof the msh member. .die member is attached to adisc 84 mounted withinl the hollow lsash member 85 and to e rotatablestem 83 ofthe han` ofthewindow opening itself. er to manipulate the various movmembers referred to, a handle mem- `provided With Which the inner extremities of the locking bolts 24 already referred to are attached 1n a diametrically opposed pivoted relation as at 86 and 87 IVith this construction, it Will be seen that .a normal and locked position of the parts is produced when the handle member 82 is rotated to a position parallel With the rail 85 on which itis mounted. On the other hand, an unlocked position of the locking bolts 24 is produced when the handle member 82 is moved to a position at right angles to the sash member 85 corresponding to a position to which the handle is moved when it is swung in the line of pull necessary to be applied in raising the Window. Spring members 86 engage Washers 87 attached to the bolts 24 at one end and rest against branches 88 of a stop member 89 having an opening 90 therein through which the stem 83 of the-locking device passes.
